Description

Technical Field

[0001] The utility model belongs to the technical field of evaporators and relates to a double-water chamber core evaporator. Background Art

[0002] The evaporator is a crucial component among the four major components of a refrigeration system. The low-temperature condensed "liquid" passes through the evaporator, exchanging heat with the outside air, "gasifying" and absorbing heat to achieve the cooling effect. Evaporators used in automobiles, in particular, can present the following problems due to long periods of driving. First, the evaporator maintains a high overall temperature, necessitating a high heat dissipation requirement and requiring rapid cooling of the evaporator. Second, the evaporator experiences vibration during driving, requiring the evaporator to be securely fixed and prevented from loosening due to prolonged shaking. Furthermore, shaking can cause the core to vibrate, exerting tension on the inlet and outlet pipes, potentially damaging them. Third, because the inlet and outlet pipes are integrated with the core, they need to be completely replaced if damaged, leading to complex and costly maintenance. A dual-chamber core evaporator was designed to overcome these issues. Utility Model Content

The side plates 2 are installed at the upper and lower ends of the core 1, and a liquid inlet 3 and a liquid outlet 4 are opened on one side of the core 1. A liquid inlet assembly 5 and a liquid outlet assembly 6 are installed outside the liquid inlet 3 and the liquid outlet 4. The liquid inlet assembly 5 and the liquid outlet assembly 6 are connected and fixed by a connecting block 7, and a connecting through hole 8 is opened on the connecting block 7.

[0019] The heat dissipation block 9 is composed of two upper and lower heat dissipation plates 10 arranged opposite to each other. Each heat dissipation plate 10 is provided with two parallel grooves 11. Flow holes 12 are provided on both sides of each groove 11. A protruding water storage tank 13 is welded on the flow hole 12. When the upper and lower heat dissipation plates 10 are spliced together, two independent water chambers are formed between the water storage tanks 13, and flow channels are formed between the grooves. A group of heat dissipation blocks 9 is composed of two flow channels, and a commutator plate 15 is installed in one group of heat dissipation blocks 9 to change the internal flow channel.

[0020] The utility model is composed of multiple heat dissipation blocks arranged in parallel, and a double-water-chamber core evaporator is formed through structural settings. This design can greatly improve the internal circulation rate, thereby achieving a good cooling effect, and the internal flow channel is changed by setting the reversing plate, which facilitates the normal operation of the whole.

[0021] There are a total of 23 heat sinks 10 from bottom to top, and adjacent two pieces are arranged relative to each other, and side plates 2 are installed at the top and bottom.
